On April 10, 2014, Margathe, Jean-Francois; Iturrioz, Xavier; Alvear-Perez, Rodrigo; Marsol, Claire; Riche, Stephanie; Chabane, Hadjila; Tounsi, Nassera; Kuhry, Maxime; Heissler, Denis; Hibert, Marcel; Llorens-Cortes, Catherine; Bonnet, Dominique published an article.Safety of Methyl 2-(2-aminothiazol-4-yl)acetate The title of the article was Structure-Activity Relationship Studies toward the Discovery of Selective Apelin Receptor Agonists. And the article contained the following:
Apelin is the endogenous ligand for the previously orphaned G protein-coupled receptor APJ. Apelin and its receptor are widely distributed in the brain, heart, and vasculature, and are emerging as an important regulator of body fluid homeostasis and cardiovascular functions. To further progress in the pharmacol. and the physiol. role of the apelin receptor, the development of small, bioavailable agonists and antagonists of the apelin receptor, is crucial. In this context, E339-3D6 was described as the first nonpeptidic apelin receptor agonist. The authors show here that 1 is actually a mixture of polymethylated species, and they describe an alternative and versatile solid-phase approach that allows access to highly pure 27, the major component of 1. This approach was also applied to prepare a series of derivatives in order to identify the crucial structural determinants required for the ligand to maintain its affinity for the apelin receptor as well as its capacity to promote apelin receptor signaling and internalization. The study of the structure-activity relationships led to the identification of ligands 19, 21, and 38, which display an increased affinity compared to that of 27. The latter and 19 behave as full agonists with regard to cAMP production and apelin receptor internalization, whereas 21 is a biased agonist toward cAMP production Interestingly, the three ligands display a much higher stability in mouse plasma (T1/2 > 10 h) than the endogenous apelin-17 peptide 2 (T1/2 < 4 min). The experimental process involved the reaction of Methyl 2-(2-aminothiazol-4-yl)acetate(cas: 64987-16-2).Safety of Methyl 2-(2-aminothiazol-4-yl)acetate
